Nano-laboratory heating plates detail the development of nanotechnology

Nanotechnology laboratory electric hot plate using simple keyboard keys, the controller design, LCD screen display, safety lock, hour meter function, as well as the high temperature alarm prompt, convenient use, heating module and control system design, intelligent process control system, separate section control, is suitable for most of the vessel, glass, ceramic, metal, none shall not, save energy, standby power consumption is less than 1 w.

Nano science and technology is based on many modern advanced science and technology, science and technology, it is the modern science (physics, quantum mechanics and chaos of the mesoscopic physics and molecular biology) and modern technology, computer technology, microelectronics technology, analysis technology) and scanning tunneling microscopy (STM) combined with the product of nano science and technology and will trigger a series of new science and technology, for example: nano physics, biology, chemistry, nano electronics and nano processing technology and nano metrology, etc.

From the research to date, there are three concepts about nanotechnology:

* species, is the 1986 American scientist Dr. Drexler in the book "the creation of the machine" proposed molecular nanotechnology. According to this concept, it is possible to make the machine of combining molecules practical, so that all kinds of molecules can be combined arbitrarily, and any kind of molecular structure can be produced. The concept of nanotechnology has not yet made significant progress.

The second concept places nanotechnology at the limits of micromachining. This is the technique of artificially forming nanoscale structures by "machining" them with nanoscale precision. This nanoscale processing technology is also pushing the limits of semiconductor miniaturization. Even with the development of existing technologies, the theoretical limit will eventually be reached. This is because if the wire amplitude of the circuit is gradually reduced, the insulation film that makes up the circuit will become extremely thin, which will destroy the insulation effect. There are also problems with heat and shaking. To solve these problems, researchers are working on new forms of nanotechnology.

The third concept comes from a biological point of view. There are already nanoscale structures in cells and biofilms. The development of DNA molecular computer and cell biological computer has become an important content of nanobiology.
